Environment
Habitat: tropical/subtropical moist broadleaf forest

Altered habitat: secondary forest

Substrate: ground surface

Disturbance: grazing, selective logging

WMT: 26.5

CMT: 15.5

MAP: 4076.0

Dry months: 4

Habitat comments: disturbed tropical semi-evergreen forest with a "high degree of disturbance in terms of various anthropogenic activities such as fire wood collection, timber logging and grazing etc... Each of the selected forest stands covers an area of more than about 25 ha of land"

Methods
Life forms: trees

Sites: 50

Site area: 0.5

Sampling methods: quadrat

Sample size: 87 individuals

Years: 2002-2003

Net or trap nights: 0

Size min: 10.0

Basal area status: not stated

Sampling comments: 50 quadrats of 10 x 10 m sizes, for tree (≥10 cm dbh.) (p. 304). Total site area=0.5 ha. However, results are given in Nº/ha. Thus, n= ( Nº/ha.)*0.5.
JA: authors appear to have screwed up and calculated per 0.2 ha figures, so I have recomputed the counts
